A Trace Inequality for the column spaces of the matrices

摘要：

Trace inequalities naturally arise in control theory and in communication systems with multiple input and multiple output. One application of Belmegas (2009) trace inequality has already been identified. Wang (20108) extend the symmetric positive definite matrices of his inequality to symmetric nonnegative definite matrices, and the inverse matrices to Penrose-Moore inverse matrices. However, the conditions of his theorems are too strong, and suitable aspect is narrow. In this paper, we give more weaken conditions.
